WS2812B - Information LEDs blinking

Hi,
have someone idea how to easy convert standard 3 LEDs for information:

example:
// LEDs
/**********************************

Information LEDs blinking
***********************************/
// If one of the following is defined here, or in the sketch, the pin will be used for the
// corresponding led function.
// They have to be enabled here (or in your sketch). Replace x with the pin number you have the LED on.
//
// NOTE!! that on some platforms (for example sensebender GW) the hardware variant can enable LEDs by default,
// These defaults can be overridden by defining one of these.
#define MY_DEFAULT_ERR_LED_PIN 9
#define MY_DEFAULT_TX_LED_PIN 6
#define MY_DEFAULT_RX_LED_PIN 5
